Question

a)  5x-25=2x+2       b) 5(x-2) = 3x +20      

Answer 1

a)
5x-25=2x+2
5x-2x = 2+25
3x = 27
x = 27/3
x = 9

b)
5(x-2)=3x+20
5x-10 = 3x+20
5x-3x = 20+10
2x = 30
x = 30/2
x = 15

Espero ter ajudado. :))

Answer 2

$A) ~ 5x-25= 2x+2 \\ ~~~ 5x-2x= 2+25 \\ 3x= 27 \\ x= \frac{27}{3} \\ \boxed{x= 9 } \\ \\ \\ \\ B) ~ 5(x-2)= 3x+20 \\ 5x-10= 3x+20 \\ 5x-3x= 20-10 \\ 2x= 10 \\ x= \frac{10}{2} \\ \boxed{x= 5}$
